Spectacles, particularly rimless drilled-lens spectables

ABSTRACT

In the case of eyeglasses, particularly rimless, drill-mount eyeglasses ( 1 ), whereby the eyeglass lenses ( 2 ) are provided with through-bores ( 3 ) on the outer edges for accommodating regions of the bridge ( 5 ) or of the temples that comprise an element ( 6 ) of the temple hinge ( 8 ), the ends of the bridge, on the one hand, and of the temples or frame elements, on the other hand, are supposed to be attached in such a manner that they can hardly be perceived optically.  
     This is achieved in that each through-bore ( 3 ) for the bridge or temple elements has two additional through-bores ( 3   a,    3   b ) assigned to it, in each instance, for passing through a plastic filament ( 9 ) that fixes these elements in place on the eyeglass lens ( 2 ).

[0001] The invention relates to eyeglasses, particularly rimless,drill-mount eyeglasses, whereby the eyeglass lenses are provided withthrough-bores on the outer edges for accommodating regions of the bridgeor of end pieces that comprise an element of the temple hinge.

[0002] There are different eyeglass configurations, where the eyeglasslenses might be accommodated in a complete eyeglass frame, or where onlyparts of the frame are configured, and the eyeglass lenses are generallyheld in approximately arc-shaped frame parts by means of nylon filamentsor the like, such as described, for example, in DD-372, DD-2062, DE-8526 267-U, DE-299 19 039-U, or DE-200 02 863-U.

[0003] Attachments by way of metal wires are shown in U.S. Pat. No.5,748,280, U.S. Pat. No. 6,070 978, or DE-295 15 008-U, whereby thereare also so-called frameless or glass-only eyeglasses, in which thebridge and the temples that carry the lens-holding frame parts, with thecorresponding hinge elements, are screwed into bores in the lens. Such aconstruction is known, for example, from DE-299 01 347-U. Modifiedversions are shown, for example, by U.S. Pat. No. 2,588,505, U.S. Pat.No. 5,659,380, U.S. Pat. No. 5,684,559, FR-607 214, or WO 97/21133, tomention only a few examples.

[0004] Attaching the frame elements directly to the eyeglass lenses bymeans of screws does lead to very good results, but an effort is alwaysmade to achieve attachment of the frame elements in as invisible amanner as possible.

[0005] This is the point from which the invention proceeds, which has asits task to achieve an attachment of the ends of the bridge, on the onehand, and of the temples, i.e. the frame parts that accommodate thelens, on the other hand, that can barely be perceived optically.

[0006] In the case of eyeglasses of the type stated initially, this taskis accomplished, according to the invention, in that each through-borefor the bridge or temple elements has two additional through-boresassigned to it, for passing through a plastic filament that fixes theseelements in place on the eyeglass lens.

[0007] Fixation of the frame elements using plastic filaments, forexample nylon filaments, opens up the possibility of an extremelyreticulated configuration of glass-only eyeglasses, since the attachmentelements are hardly visible at all. Because of the possibility of usingtransparent plastic filaments, this effect is additionally supported.

[0008] Embodiments of the invention are evident from the dependentclaims. In this connection, it can be provided that the through-boresare arranged in alignment, whereby the bore that is farthest from theedge of the glass forms the holder for an angled end of the wire thatforms the temples or the bridge, and the other through-bores serve topass through the fixation filament and to accommodate the fixation knot.

[0009] Another embodiment of the invention consists of the fact that thebore that is adjacent to the holder bore for the wire ends has a regionhaving a smaller diameter and a region having a greater diameter, toaccommodate the fixation filament knot. This configuration makes itpossible to provide an easily enlarged drilled region in the eyeglasslens, in which the end knot of the fixation filament can be positioned,so that no part of the filament projects beyond the outside contour ofthe eyeglass lenses that have been fixed in place.

[0010] Very firm fixation of the wire end on the eyeglass lens, in eachinstance, can be achieved in that during fixation of the wire end thatis inserted into the through-bore, the fixation filament loops aroundthe wire in the region of the outer edge of the eyeglass lens, passesthrough the first through-bore as a double filament, in the side of theeyeglass lens that faces away from the wire, passes by the inserted wireon both sides, runs into the other through-bore after forming a filamentX on both sides, outside on the wire, and is knotted in thatthrough-bore, forming the tension that is necessary for fixation.

[0011] Other characteristics, details, and advantages of the inventionare evident from the following description, as well as on the basis ofthe drawing. This shows, in

[0012]FIG. 1 a simplified spatial view of a pair of eyeglasses accordingto the invention, with the nosepiece fixed in place and loose, as wellas in

[0013]FIG. 2 four steps of the knotting and fixation technique of theattachment wire in the edge region of the eyeglass lens.

[0014] The eyeglasses designated as a whole as 1 are configured asso-called glass-only eyeglasses, i.e. the lenses designated as 2 do nothave any frame that holds them, rather each eyeglass lens is equippedwith three through-bores, designated in general as 3, on the outer edge,whereby these through-bores are designated as 3, 3 a, and 3 b in FIG. 2,for a better understanding. These through-bores serve, among otherthings, to accommodate an angled end 4, whether of the bridge indicatedas 5 or of the element indicated as 6 of the frame part 7 in front of ahinge 8, not shown in detail, the configuration of which is notimportant here.

[0015] In this connection, the bridge 5 or the hinge element 6,respectively, is fixed in place on the eyeglass lens 2 by means of anylon filament 9, specifically in the manner shown in FIG. 2. First, alooped end of the nylon filament 9 is passed through the bore 3 b thatlies closest to the outer edge 2 a of the eyeglass lens 2, the filamentsare looped in an X on the surface of the lens 2 and passed through theadjacent bore 3 a. The loop that is formed is then looped around theouter edge 2 a of the eyeglass lens 2, as is evident from FIG. 2, thirdsegment. Now the bridge or the corresponding element 6, for example,respectively, is threaded through and inserted into the inner bore 3with its angled end 4, the filament is pulled taut, and knotted.

[0016] As is particularly evident from FIG. 2, the through-bore 3 a isconfigured in stepped manner, i.e. it has a region having a smallerdiameter 10, which is positioned in the direction of the outside of theeyeglass lens, and a region having a larger diameter, designated ingeneral as 11, which serves to accommodate the knot, not specified indetail.

[0017] Of course the exemplary embodiment of the invention can bemodified in many different ways, without leaving the basic idea of theinvention. For example, a small disk can subsequently be pushed over thetwo filament ends to be knotted, which lies against the edge of thetransition from the bore region 11 to the bore region 10, in order tofix the knot in place more firmly, and the bridge shapes can have anytype that is usual for eyeglasses, as can the hinges, and the like.
